Compact wireless lavalier set for presenters

The Ruth's sister 71003477 system pairs a clip-on condenser microphone with a belt-pack transmitter and a pocket-sized receiver, giving teachers, lecturers and karaoke singers cable-free voice pickup. Its omnidirectional capsule captures speech from any angle while the 95 cm cable keeps the mic close to the mouth.

20-metre range with 80–12500 Hz response

The UHF link stays reliable up to 20 m in open space, covering a typical classroom or small stage without drop-outs. Frequency response from 80 Hz to 12500 Hz reproduces vocal fundamentals clearly, though deep bass and very high sibilance fall outside the passband. The 600 Ohm output matches standard mixer and camera inputs directly.

Upgrades wired lapel mics and built-in camera audio

Replacing a tethered lavalier or on-camera microphone removes cable trip hazards and lets the speaker move freely across a stage or whiteboard. The jump is worth it whenever mobility matters more than absolute studio fidelity; users needing longer range, rechargeable cells or multi-channel operation will need a different system.

Questions about this item

Can I run the 71003477 transmitter on rechargeable AAA cells instead of the 1.5V alkaline specified?

The transmitter requires one 1.5V AAA battery, not included. Rechargeable AAA cells typically deliver 1.2V and may reduce operating time or range.

How do I confirm the 71003477 system is transmitting correctly within its 20m range after setup?

Power the receiver with a 6F22 9V battery, clip the lavalier to the transmitter, speak at normal volume and verify clear audio at the receiver output up to 20 metres.

What comes in the 71003477 package and which batteries must I buy separately?

Box includes one receiver (98×63×28 mm), one transmitter (105×40×14 mm) and one lavalier microphone with 95 cm cable. Purchase one 1.5V AAA for the transmitter and one 6F22 9V for the receiver separately.
